Initially, we apply TE to a classical age-stratified SIR model and find that the inferred patterns align with the interaction structure of the population, as defined by the age-mixing matrix. Applying this methodology to the COVID-19 pandemic data from Spain, we illustrate how TE can capture temporal changes in individual behavior. Furthermore, we demonstrate that incorporating the inherent dynamics of the epidemic process allows us to create a coarse-grained representation of the time series, providing richer information than raw data. We argue that this macro-level perspective is enhanced by the effectiveness of causal analysis across different scales. Our findings underscore the potential of informational approaches to retrospectively track behavioral adaptations during a pandemic, offering valuable insights for tailoring strategies to control disease spread. This paper paves the way for future research into using such methods for model-free estimation of contact patterns during pandemics. info:eu-repo/grantAgreement/ES/DGA/E36-23R-FENOL info:eu-repo/grantAgreement/ES/MICINN/PID2020-115800GB-I00 info:eu-repo/grantAgreement/ES/MICINN/RYC2021-033226-I info:eu-repo/semantics/closedAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.4 2024 PHYSICS, MATHEMATICAL 13 / 61 = 0.213 2024 Q1 T1 PHYSICS, FLUIDS & PLASMAS 17 / 41 = 0.415 2024 Q2 T2 0.705 2024 Condensed Matter Physics 2024 Q2 Statistics and Probability 2024 Q2 Statistical and Nonlinear Physics 2024 Q2 4.2 2024 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Aleta, Alberto Universidad de Zaragoza (orcid)0000-0002-1192-8707 Rodrigues, Francisco A.
